    About Hair Drug Tests

    What is a hair follicle drug test?

    A hair follicle drug test is a type of drug test that analyses a sample of an individual’s hair to detect the presence of drugs or their metabolites, which are substances produced when the body processes drugs.

    How far back does a hair follicle test detect drugs?

    Hair drug testing can provide information about an individual’s drug use over the past 90 days (three months), making it a useful tool for employers, legal authorities and healthcare providers to detect long-term drug use.

    Does colouring your hair hair affect drug testing?

    Colouring your hair doesn’t typically affect drug testing results, as drug traces are detected within the hair shaft, not the hair’s outer pigment. However, excessively bleaching or dyeing hair may damage the shaft, potentially affecting the accuracy of the test.

    What Drugs Are Detected In A Hair Test

    Safework Health performs hair drug testing based on several international guidelines and procedures including those published by the (International) Society of Hair Testing.

    Unlike urine or saliva testing, there is no specific Australian Standard for detecting drugs of abuse in hair.

    Hair drug tests can quickly and accurately detect the presence of a wide range of illicit and prescription drugs including:

    • Amphetamine Type Stimulants (speed, dex, ice and XTC)
    • Benzodiazepines (sleeping tablets, relaxants)
    • Cannabis (marijuana, THC)
    • Cocaine
    • Opiates (Heroin, Codeine, Morphine, Oxycodone, Fentanyl)
    • Benzodiazepines (Diazepam, Alprazolam, Other sedatives and anxiolytics)
    • Synthetic Cannabinoids (K2, Spice)
    methamphetamine;

    How Are Hair Samples Collected

    During testing, technicians will cut a lock of hair of around 200mg from the vertex of the scalp, which is the area at the back of the donor’s head. The amount of hair samples taken is equivalent to the size and thickness of a small pencil. We routinely collect the lock of hair close to the scalp.

    • Hair is cut, not pulled
    • Typically, 100–120 strands are collected
    • Collection is quick and discreet
    • Full chain of custody procedures are followed

    If there is no or insufficient scalp hair (i.e., the hair length is ≲ 1 cm) beard hair can be used but it is not possible to accurately determine the time period covered by such a sample because beard growth is highly variable between men.

    Safework Health does not recommend using, nor does it analyse body hair, as drug uptake rates are variable, location-dependent and the rate of growth of body hair is poorly understood.

    Hair grows at a rate of roughly 3.8 cm every 3 months so the length of a hair sample determines the time-span that can be examined. If the hair is long, we can perform a segmental analysis – cutting the hair into monthly segments (around ~ 1 cm) – to get a progressive picture of the donor’s drug use.

    Chain of custody procedures are undertaken to ensure the results will withstand examination in a court if required.

    Benefits And Limitations Of Hair Testing

    What are the benefits of hair follicle testing?

    Overall, hair drug testing offers a comprehensive and reliable approach to detecting drug use over an extended period.

    • Extended detection window: Hair testing can detect drug use over a longer period (90 days) compared to other methods such as urine or saliva testing. It can detect drug use spanning several months, providing a comprehensive overview of an individual’s drug history.
    • Resistance to adulteration: Unlike other approaches, hair testing is highly resistant to tampering or manipulation of the sample. This makes it a more reliable method for detecting drug use, as it is difficult for individuals to interfere with the test results.
    • Monitoring long-term drug use: Hair testing is particularly useful for monitoring long-term or chronic drug use patterns. It can provide insights into an individual’s drug habits over an extended period, making it valuable for assessing substance abuse issues and determining appropriate interventions.
    • Reliability in safety-critical environments: Hair testing is commonly used in safety-critical environments such as workplaces and family law proceedings. Its extended detection window and resistance to tampering ensure reliable compliance, particularly in cases involving child custody and visitation rights, where the wellbeing of children is paramount.

    What are the limitations of hair drug testing?

    While hair drug testing offers certain advantages, it’s important to recognise its limitations:

    • Inability to detect recent drug use: Since hair grows gradually from the scalp, it typically takes about 10 to 14 days for drugs to show up in the hair follicle. This means that recent drug use within the last week or so might not be detected in hair samples.
    • Limited detection of infrequent drug use: Hair testing may not be sensitive enough to detect sporadic or occasional drug use, especially if the drug concentrations are low or if the hair sample is short.
    • Invasive collection process: While hair collection is generally non-invasive compared to methods like blood tests, it still requires the removal of a hair sample, which some individuals may find uncomfortable or objectionable.

    Frequently Asked Questions About Hair Follicle Testing

    How far back does a hair follicle test detect drugs?

    A standard hair follicle test can detect drug use over the previous 90 days, based on analysis of a 3 cm hair sample taken from the scalp. As hair grows at roughly 1 cm per month, longer samples can extend the detection window further.

    Can a hair follicle test detect one-time drug use?

    Hair follicle testing is best suited to identifying repeated or chronic drug use rather than isolated, one-off consumption. Single or very infrequent use may not always be detectable, particularly if drug concentrations are low or hair samples are short.

    Does hair colour or bleaching affect results?

    Normal hair colouring generally has minimal impact on test results, as drugs are detected within the hair shaft rather than the pigment. However, excessive bleaching or repeated chemical treatments may damage the hair structure and can potentially reduce detection sensitivity.

    What if I don’t have enough scalp hair?

    If there is insufficient scalp hair, beard hair may be used as an alternative sample. While this allows testing to proceed, body or facial hair grows at variable rates, meaning the exact timeframe of drug use cannot be determined as precisely as with scalp hair.

    Is hair testing accepted in Australian courts?

    Yes. Hair follicle testing is widely accepted in Australian courts when conducted using proper chain of custody procedures and accredited laboratory analysis. It is commonly used in family law, child custody matters, and other legal proceedings requiring long-term substance use evidence.

    How accurate is hair follicle drug testing?

    Hair follicle drug testing is highly accurate when confirmed using Liquid Chromatography/Mass Spectrometry (LC/MS) technology. This method provides precise identification of drugs and metabolites, reducing the risk of false positives and ensuring results are legally defensible.

    Can detox shampoos beat a hair test?

    No. Detox shampoos and external cleansing products cannot reliably remove drugs embedded within the hair shaft. Because substances are incorporated internally as hair grows, surface treatments are ineffective at altering results from properly conducted hair testing.

    Do you offer on-site collections?

    Yes. On-site hair sample collection is available nationwide through trained collectors, as well as at designated collection centres. All collections follow strict identification and chain of custody procedures to ensure accuracy, consistency, and legal defensibility.
